GASEMENT-WINDOW OPERATOR.

Application filed June 28, 1926. Serial NO. 119,174.

The present invention relates to improvements in window operatingdevices, and more particularly to devices for the operating of casementwindows.

The primary object of the invention is to provide a casement windowoperator whereby the window sash may be operated from the inside of thebuilding without the necessity of raising or removing of a screensupported by the window casing inwardly of the sash.

A further object of the invention is to provide a novel type of casementsash operators which may be operated for swinging of the sash withoutthe necessity of reaching out of the window when desiring to swing thesash to a closed position in the window frame.

A still further object of the invention is to provide a device of thischaracter which is extremely simple and durable in construction, whichmay be n'ianufactured at a relatively low cost from stock rods ofasuitable gauge, and which devices are of such construction as to permitof the sash being locked in a closed, opened, or intermediate position.

Other objects and advantages of the inven tion will be apparent duringthe course of the following detailed description, taken in connectionwith the accompanying drawings forming a part of this specification andin which drawings:

Figure 1 is a transverse section through a casement window constructionand showing the improved device applied thereto for operating of thecasement sash.

' Figure 2 is a transverse sectional view similar to Figure 1 butshowing the operator in a locked position for retaining the easementsash in a closed position'in the window frame.

Figure 3 is an enlarged detail sectional view on line 3-3 of Figure 1and looking in the direction of the arrows.

Figure 4 is an enlarged vertical section on line ie-40f Figure 2,looking in the direction of the arrows and portion of the easementwindow construction.

Figure 5 is an enlarged fragn'ientary section on line 55 of Figure 1,and showing the construction of portion through which the operatorextends.

Figure 6 is an enlarged fragmentarysection on line 66 of Figure-2 andillustrating the locking arrangement for the operating device.

Figure 7 is an enlarged fragmentary section on line 7 --7 of Figure 2.

showing merely the lower the window screen at that Figure 8'is anenlarged fragmentary perspective view of the hinge connection betweenthe operating device and the easement sash.

Referring to the drawings in detail, and wherein similar referencecharacters designate corresponding parts throughout the several views, Adesignates a window casement or frame provided with thecasement sash B,C a window screen closing the window opening inwardly of the casementsash B; and D the improved casement sash operator for swinging of thesash B to an open or closed position with respect to the frame A.

Referring to the window frame or casing A, and which is of usualconstruction, the same comprises a sill 10, stiles 11, and the usualstop beads 12 carried by the confronting faces of the stiles 11intermediate the longitudinal edges of the stiles and which beads formstops for the easement sash B.

The casement sash B for closing of the opening of the frame A, embodiesthe lower rail 14 and the side rails 15, the sash being of that typewhich is hung upon one vertical side to one of the stiles 11 as by meansof suitable hinges 16 having one wing secured to the stile and itsopposite wing'secured to one of the side rails15 of the sash. With thistype of casement window construction, and as will be observed in Figure2, when the sash is moved to a closed position, the'same abuts againstthe stiles 11 for limiting inward swinging of the sash. I

The constructon of the window as shown, is commonly known in the art asan outwardly opening casement window.

The screen C, and which may either be of the sliding or hinge type, inthe example shown embodies a bottom rail 17 resting upon the uppersurface of the sill 10, and side rails 18 abutting against the inneredges of the stop beads 12. The screen C in casement windows of thistype must necessarily be dis posed inwardly of the easement sash inorder to permit of the sash being swung outwardly to an openpositioinand as will'be observed in Figure 2 when the sash is swung to aclosed position, a space the width of the beads 12 is provided betweenthe sash and screen, and in which space the major portions of the operating means D come to rest when the easement sash is swung to a closedposition by the operating means.

Referring now to the easement sash operator D, the same embodiesanoperating lever 20 in the form of a bell crank, providing a throw arm21 and a relatively short ofiset operating arm 22. The operating lever20 is formed from a flat bar of metal of a suitable gauge, and ispivotally mounted'at 'its'apex as by means ofa suitable pivot pin 23 tothe upper surface of the sill 10. 'l hispivo't pin or fulcrum 23 may bein the form of a headed screw turned into the sill at a point relativelyclose to the outer side of the screen C and in the space formed betweenthe'sash B and the screen. Formed at the outer end of'the throw arm 21,as by means ot'bending up an edge portion of the arm, is-a stop 24. Theofiset operating arm 22 extends'inwardly through an elongated recess 25provided in the bottom ed 'e oi the'botto'n'rrail 17 of the screen to aposition whereby the same may be readily grasped for swinging of thelever 20 about its fulcrum, pin 23 from a position inwardly of thebuilding. The inner end of the arm-22'may be provided with asuitableoperating linob'26. A yie'ldable flap27 may be secured to the outer sideof the bottom rail 17 above the recess-'and extend downwardly over therecess in a manner for closing of'the recess and yet permitting of imemovement 01: the arm'22 along the recess. As will be observed in Figures5 and 7, the relatively flat-operating lever 20 lies flat upon'the upperface otthe sill 10. 'Pivotally connected adjacent the outer end of thethrow arm 21, and upon the'upper'side olthe arm, as by a suitable pivotpin 28, is a link 30 having a recess 31 provided in one longitudinaledge thereof and into which the stop 24 of the throw a'rinmoves :Whenthearmand link are in substantial alignment as illustrated in Figure 1. Theouter end of the linkSO is pivotally connected asby means of a suitableL-sh'ap'ed bracket 35 'to the lower rail 14: of the sash B at a pointsubstantially midway between the siderails ThisL-shaped bracket 35, and"as will be observed'in Figure 4, is secured to the inner face of thelower rail 14 at a point spaced slightly upwardfroin the lower edge ofthe rail for allo'wing'the bracket to clear the stop 36 01 the sill 10whenthe sash is swungto'a-closed position.

Securedatone end to the operating arm 22, and preferablyadjacent theknob '26, and means of a suiItable'ri-vet or the like .39, is anareu'ate shaped locking plate 40 extending in an arc concentric to thepivot pin 23. This locking plate or arm 40, adjacent its connectionwith'th'e operating arm 22,'is provided with an upwardly oflset portion41 which overlies the arm '22, and provides a shoulder 42 adapted toengage one edge of the arm for rigidly retaining the locking plateagainst swinging movement about'its securing pin 39. The locking plate40 is provided with a series ofapertures 44 which are adapted to receivea locking pin l5carried by 'the sill 1O 'and'projecting upwardly fromthe upper face of the sill in a path of the arcuate movement o f thearcuate sh'aped locking'plate. This arcuate shaped perforated lockingplate 40 and co-acting lockingipiir mserve-as means for adjustablylocking the easement sash B in various ang g'ular relations with respectto the window frame A, nd in the dotted line showing in Figure "1,th'ecentrally disposed aperture of the locking plate is shown engaged by thepin 45 for retainingthe sash in a partially opened locked position. Theolls'e'tjprovided in the attaching end of'the'locking pl'ate 430disposes the major portion of the plate which provided with theapertures 44, in surface contactupon the upper face of the sill 10 andit can be seen that upon grasping ot the 'lin'ob 26 that the Operatingarm 22 may be sprung upwardly for withdrawal of the locking platelroin'the pin 45}when desiringto adjust-or op'erate'th'e sash 'B.

WVhen the sash B is swungto a rull 'opened position, the arm 21 and 1ink30wi1lbelocked by means of the stop 24am recess 31, i'nya position forretaining the sash in an opened position, and in 'which position "thelocking plate 40 need not'necessarily engage the lo'cking pin 45. Whenthe sash is in "a fully closed position as in Figure2,the aperturenearest to the operating arm 22 will'receive the locking pin 45. lVhen'desiring to "open the sash from a fully closed position as in Figure 2,'the' operator first grasps the! knob 26 and upon a slight upward;pullin*disengages the arcuate 'loc'kingjplate '40 from the locking pin 45,an'd whichfreeing'dfi the arm 22 will allow the OperatingleVerQO 'tobeswung about its fulcrum 23"for swinging of the sash B about its hinges16. v I i The recess 25 provided in the loweredgeof thescreen C, isofalengthto allow the free end of the locking plate 40 to {pass beneath thescreen when the operator is'in "a position for retaining the easementsash in a "closed position, and as will be observedin Figure 2 a verysmall portion ofthe operating d'evice extends inwardly past the screenC'when the sash is in a closedposition. I c

From the foregoing description'it willbe apparentthat an extremelysimple yet elficient type of casement sash operators h'as been providedwhereby the sasheso'f casementwindows provided with screens disposedinwardly of the sasln'may be readilyoperated'without raising of thescreen, and embodying featines-whereby the sash m-ay be locked in eitheran open, closed, or intermediate positions.

Changes in detail may be made "to "the specific form of the invention"herein shown and described, without departing from "the spiritofthe-inventio'n or the'sco'pe ofth'e' fol lowing claims.
